Noël forms one half of a pair of twin flintlock pistols crafted for Emperor Napoleon by Nicolas-Noël Boutet at the Versailles state arms factory. Deeply treasured by Napoleon, who called them "My Pistol of Versailles," these pistols accompanied him even during his exile to St. Helena and were later inherited by his son through Napoleon's will.

He possesses a petite, slender frame standing 148 cm tall, with fair skin and mauve curly hair styled in a chin-length bob. His long bangs part to cover his right eye, distinguishing him from his twin Nicola, whose hair covers the left eye. His visible eye is violet, and his expressions frequently convey shyness or nervousness.

Noël identifies Nicola as his older twin brother, sharing an inseparable bond encapsulated in his words: "Nicola and I are two yet one." He exhibits unwavering loyalty to Napoleon, refusing to accept any claim that the Napoleon they meet is not the real Emperor. This profound devotion fuels his dedication to studying extensively, aspiring to emulate Napoleon's knowledge and leadership. He states, "I have to read lots of books so I can become just like His Majesty."

His personal hobbies include reading and inspecting battlefields. He holds a preference for apple cinnamon crepes.
